Utility-aware Payment Channel Network Rebalance
Summary: Introduce Utility-Aware Rebalance (UAR) for payment-channel networks: transaction utility = channel weight × amount / receiver balance, with per-channel budget and user flow-conservation constraints. Prove UAR NP-hard and inapproximable; propose Circuit Greedy and UAR_DC heuristics achieving ≥3.16× utility over prior work. (summarized by gpt-5-mini on Feb 09 2026)
